About
Ostional is an exposed beach-break surfing spot on the Cuajiniquil Coast within a protected wildlife refuge. Surf is described as very consistent and often powerful, with both left and right waves. Working conditions are repeatedly linked to mid-to-high tide (with some guidance preferring rising tide) and a west-to-southwest-family swell, while east winds/offshore conditions are described as favorable—especially during the dry season. Typical ride lengths are commonly reported around 50 to 150 meters, with good days extending toward roughly 150 to 300 meters (and exceptional long rides also described). Wave power is characterized as hollow/fast/powerful in some descriptions, with the overall feel ranging from mixed to hollow peaks depending on conditions. Shorebreak is described as moderate, and the surf zone can include hazards such as reef (reported by sources) and driftwood/debris, especially near river mouths. Safety and access are strongly shaped by the resident turtle population. During major turtle nesting (Arribadas), access may be restricted or require a guide, and activities can be limited during peak arrival periods to protect nesting turtles. The refuge also imposes rules such as no motorized vehicles on the beach, no camping in the refuge, and restrictions on night lighting during turtle viewing. Logistically, Ostional is reached via dirt roads from Nosara, and rainy-season conditions can make access much harder due to rough/unpaved roads and river crossings—sources commonly note that 4x4 can be essential. Visitors are also cautioned that rip currents can be strong on larger swells, and emergency/rescue support may be limited on-site, so planning and local guidance are important when conditions or access are challenging.
